Maxspect Razor R420R LED Light Fixture
Information

Slim & Elegant
Built with a slim and low profile body, the R420R LED Lighting System is design to seamlessly merge into your living area with elegance. The R420R also comes with both pendant mount hanging kit as well as tank-top mounting frame (adjustable from 28.3"-42.5"), whichever suits you better.

Overall dimensions: 27" long, 10" wide and 0.9" thick.

User ProgrammableWith 2 channels and 6 time-points: users can program their own photo-period for their aquariums and fully control the intensity of light their aquarium will receive from dawn to dusk.

Aerodynamic Design The R420R Lighting system deploys an ingenious aerodynamic design which draws cool air from underneath the fixture, through its body which also serves as a large heat sink, to dissipate heat passively.

Redefined EfficiencyThe R420R LED Lighting System redefines the term efficiency, 100% passively cooled, utilizing highly efficient high intensity LED chips from Cree, drawing 160W of power but can out-perform 400w metal halide fixtures.

Enhanced Growth and ColorationThe Razor Lighting system is designed to provide all ranges of color spectrum required by corals and plants to enhance their growth rate, improve their coloration and at the same time give your aquarium the most aesthetically pleasing combination of colors. The Razor will meet the requirements of even the most sophisticated group of reef hobbyists.

410nm/420nm Super Actinic The Razor Lighting system also utilizes the 410nm/420nm Super Actinic LED chips: the spectrum that is crucial for the success of any reef and water plant aquariums. It is required by Chlorophyll A for photosynthesis, where absorption peaks at 412nm.

Passive Cooling
The Razor Lighting system is designed to be 100% cooled passively. The body of the Razor is crafted entirely in aluminum, serving as a large heat sink. Together with an ingenious aerodynamic design, cool air is channeled through the bottom of the fixture and heat is dissipated through the aluminum chassis. Pre-installed and temperature-controlled fans that turns on only when the temperature rises past 120F.

Latest in LED TechnologyUtilizing the latest high performance high intensity Cree XLamp®, XT-E and XP-E LED chips, equipped with 90-degree optics. The Razor will consume less power yet produce more PAR (Photosynthetic Active Radiation) for even your most demanding corals.

Have a smaller tank? No problem!
Check out the Maxspect Razor’s little brother, the Maxspect Nano Razor. It’s perfect for nano reef aquariums—you can even attach two together if you upgrade to a larger tank later.

Comments:I must admit that I had very high expectations for this light. That said, it's a very solid product.
Pros: pretty easy to set your own program and continuously refine it. Light quality and color (I have the 16K) is nice. One single unit with one power cord is clean. Run's very quiet.
Cons: definitely a disco light effect visible on the gravel. Would be even better if there were two more programmable time slots; I will end up adding a separate timer to effectively add them. The 1% blue channel works well as a moonlight, but would be even better if that amount of light was half as bright. Finally, I wish that once it's set to custom program mode (what they call Auto mode), the program dial would default by starting in that mode, rather than having to cycle through to it. One single input dial is clean, but it does have limitations.

Comments:I have had two 420's (M16000) on my 225 gallon for about 2 years. The way that they turn on gradually in 6 time phases is fantastic! Why the lower review?...In just 2 years most of the Blue bulbs have blown! I now only get a yellowish light due to the predominance of warmer lighting. There doesn't seem to be a way to change the CREE bulbs either! Second issue; there are three groups of LED's and they are inset about 6" from each side and about 3.5" from each of the other groups. It would be great if they were on a "slide" that allowed them to move back and forth over the length of the unit. These units are 27" long but all of the lighting is packed into 16" of length in the middle with two fans separating each hub of LED's. Not very efficient if you are trying to put light where you need it.

Comments:I bought this for my 60 gallon cube and couldn't be happier with it. I'm still stepping up the output and will probably stop before I get to 100%. I had some concern in converting from halide and T-5 but I've found the 24 inch 120 watt is plenty of power (is it ever really enough?) and the corals seem to love it. I would definitely recommend this fixture.

Comments:WOW! Fellow Aquarists, come out of the Dark Age with the R420R. I had been using a Marineland LED strip/bar which gave me no support for corals. Switching to the Razor R420R 27" 1600 (160 watts) has really 'opened my eyes'!! In just a couple of days, all of my corals are open and thriving under this amazingly flexible lighting.
Interestingly, the colorations of my fish have also been noticeably enhanced as well. I keep asking myself, 'What took you so long to make the switch to the Razor 420R?'

Comments:to compare my old 10yr 2200.00 led fixture to this razor 420r is like a rock to a grain of sand. this razor has pushed ahead aquarium lighting 20 years.. only thing it lacks is a more precise solar controller with cloud cover and moon phase.

Comments:Very well made - Controller is ver user friendly - Color blending is beautiful. Intensity on this light is amazing. My tank is 30" deep and I have soft corals and LPS. Make sure you acclimate your corals to this light - start out at a maximum of 30% intensity and work your way up 5% per week - you will be very happy with this product.
Thanks,
Joe
